  • Patent number: 10442167
    Abstract: The present invention relates to a ballistic cloth using a unidirectional aramid sheet and a polyethylene film and a method for manufacturing the same and, more particularly, is characterized in that aramid multifilament layers, which have monofilaments stacked and arranged in one direction, are arranged perpendicularly, a polyethylene film, which plays both the role of a binder and the role of protecting the sheet surface, is arranged between the aramid multifilament layers to manufacture a ply, and the ply is inserted into a mold and undergoes a pressing process and a cooling process, thereby manufacturing a ballistic cloth. A ballistic cloth manufactured by the method according to the present invention is advantageous in that use of a polyethylene film having a low softening point between unidirectional aramid sheets improves adhesiveness between the sheets and also improves the slip factor when the same ply is stacked, thereby exhibiting excellent ballistics performance.
